It depends on what the claims in the patent are, but take my word on it ....ornamental designs are difficult to fight because everyone will interpret the similarities and differences differently.

How it was explained to me.
The drawing is not the infringement, drawing the object in CAD is the same as ripping a song you own on a PC. (not illegal)
Posting/distributing it is where legallity comes into play, because it could be argued that each download is a lost sale because downloading the stl file is pretty clear intent the file will be printed.
Example, you just bought yourself a new

In Canada(or any other common wealth country) and the USA a court can only determine damages/infringement to a patent holder based on monetary loss.
Regardless what the written law is.....The fact remains you can build patented things for private use if you built them yourself, otherwise everyone would need to do a patent search every time they wanted make anything.
Consider this.......If you p

I might of missed it but......liability for copying any protected IP only applies if you are trying to make money off it.
Nothing is stopping you from building any design you can get your hands on...you just can't sell it.

Check the com speed in the config.h of the firmware and make sure it matches the com speed in the software in windows or MAC your using to connect to the machine.
Another point to check is in windows it usually installs the USB com port at 9600 bits per second, where the fw needs 115K or 250K to connect I set mine to max. You can fix this from windows device manager.

You might want to check the diameter of the fillament feeding your extruder.
If your hotend intake is drilled to exactly 1.75mm or 3mm, the plastic fillament your using might be over that diameter.

A few things that can cause various amounts of shifting(lost steps)
-stepper drives are not adjusted properly. (need to increase current going to the motors)
-Firmware or print speeds are too high for your machine.(try lower print speeds)
-Belts are too tight
-Damaged belts(metal reinforcement/bands in the belts are broken)

For the hardware you have 4 areas to deal with.
1- the 3 axis motion of the machine to hook up(x,y and Z)
In the stratasys machines they use 8 wire stepper motors, so you need to wire up the motors so they are 4 wires to use them with pololu or stepstick (4 wire stepper drivers)
2- the head uses 2 brushless motors so you need to find brushless motor drives to run those.

Claiming ownership of the designs posted under tos is one thing, but it can be argued. I'm sure makerbot's lawyers are saying the opposite because they don't have to go to court and enforce it......it's just another # to add to MBI's bill....lol....every lawyer is confident with their work when they take your money.
The way I see it is taking ownership of a design and distributing it when the

One CD has the catEX software, and the second is the controller CD that has the web update utility for the FW....open the controller CD using "my computer" and browse for it.
It might be in a folder called gifts, or you could always call the reseller and ask them for MaracaEX so you can put your CMB files on the machine.

You can read and write to the the eeprom using hyperterminal from the Diagnostic port on the back of the machine.
Look on the controller CD that came with your machine, install maracaEX. Go to the install directory and look for a PDF that says controler help, in that doc you will find the hyperterminal commands for the machine.
The eeproms are DS24XX based.

@davew_tx: take an image of the hard drive from your machine before you use the chips, then after you used the chips just write the image back to the hard drive and your back in action.

Given today’s situation, It's more productive for us as a group to start something new and completely open source owned and operated by the users..... not vendors.

I'm sure there are lots of us willing to help you get it all worked out. From what you described above your not too far off.
Post as much info as you can about your setup (Stepper motor model numbers, RAMPS Version, pictureS of your hotend..some pics of the RAMPS board and the machine.

I agree - get more powerfull motors
This might be off topic.
Cooling motors (either water cooled or peltier) could have merit if you have your machine enclosed AND you want to have a really high enclosure temp.
If they are peltier cooled they would also help heating the enclosure.
Some materials you need a really high enclosure temp to get good results. (PPSF, Ultem and PC run ....~125oC)

You could have it cool at a slower rate by PWM if your circuit can handle it or simply using a simple "ON", "OFF" cycle.
I think the major disadvantage is the weight of the heat sink on the Y axis.
